A further object of my invention is topr ovide a novel processor treating alloys and Still another object of my invention is the provision of a novel bearing member which;

Similar reference charactersdesignate similar parts in the different views? p v In carrying my lnventlon into effect, the metal tobe treated is cooled in an oleoresinous substance, such ,as..-turpentine, while heated to a temperature above the boiling point of the oleoresinous material; and, prefcvicled;

erably between such point and the'point at which the metal treated fuses; V I v v p In treat-mg bearing, such as ls'shown in the drawing, the upper and lower members; -1 and 2 respectively, thereof are first heated to a temperature as high as thefboiling point tine. 1
